Have "limit=1" tokenizers replace tokens instead of disabling "Browse"

Summary:
Fixes T9984. When a tokenizer only allows one selection (like "Task Owner:" or "Land Onto Branch:"), keep the browse button active but have it //replace// values.

Also, have "Create Subtask" default to the system default status, so subtasks of closed tasks are not also closed.

Test Plan:
  - Browsed an empty limit=1 tokenizer.
  - Replaced a full limit=1 tokenizer.
  - Browsed an empty no-limit tokenizer.
  - Browsed more tokens into the no-limit tokenizer.
  - Typed some tokens normally.
  - Created a subtask of a closed task.
